In the opposite figure, when the angle θ increases, it will affect the horizontal velocity Vx and vertical velocity Vy. Which of the following statements is right?
Understand the Problem
The question is asking which scenario correctly describes the effects on horizontal and vertical velocities (Vx and Vy) as the angle θ increases. This involves understanding the relationship between the angle and the velocities in the context of physics, particularly dynamics.
Answer
Vx decreases, the apparent weight decreases.
The correct statement is C: Vx decreases, the apparent weight of the body decreases.
Answer for screen readers
The correct statement is C: Vx decreases, the apparent weight of the body decreases.
More Information
Increasing the angle θ results in a decrease in the horizontal velocity component due to the cosine function's behavior, while the vertical component increases with the sine function.
Tips
A common mistake is confusing the behavior of trigonometric functions with changes in angle.
